3- Raise the header. 
4- Put the range shift lever to the appropriate position. 
 
  Operate the main shift lever and range shift lever 

only after the engine speed is over 1600 rpm. 

 
5- Push forward the main shift lever from “N” slowly to 

move the machine. 

 

 

[Precaution] 
Move the main shift lever from “Forward” to 
“Reverse” or from “Reverse” to “Forward” after the

brake pedal to the floor, and the machine will be 
stopped. 

  The linked main shift lever and brake pedal will 

return to “N” automatically. 

 

 

[Precaution] 



 

Main shift lever can not return to “N”, and the 
machine can not be stopped if the brake pedal 
is not stepped to the floor. 



 

Emergency stopping has only the function of a 
traveling. Neither a threshing part nor a header 
part stops. 

 
 
 

 

4. Traveling 

 

 

The center of gravity of this machine rises 
when there is a paddy in the grain tank, 
there is fear of the fall, and it is very 
dangerous. Empty the tank. 

 

 

● 

No person other than the driver is 
allowed to get on the machine. 

● 

Do not drive the machine on a ground 
with an inclination over 10 degrees in 
the four directions. Otherwise, the 
machine may fall over. 

● 

Check the surroundings before starting. 

● 

Wear the safety helmet for your safety. 

● 

Pay full attention to the road side and drive 
slowly on a slope, narrow road or those 
road segments with thick growth of grass. 

● 

When changing the direction of 
traveling, be sure to give hand signals, 
and notify the moving direction of 
others or the machine. 

● 

Avoid long-distance traveling that may 
cause damage to the crawler. 

 
1- Fold the co-worker backrest upward and retract it. 
2- Withdraw the assist grain deck. 
3- Put the threshing clutch lever and header clutch 

lever to “OFF”. 

4- Raise the engine speed by the accelerator lever. 
 
[Precaution] 
Be sure to adjust the engine speed to the point that 
tachometer hand falls in the “Green Zone”. Otherwise, 
the machine may be damaged. 
 
5- Raise the header from the ground to 30cm or more.. 
6- Put the main shift lever to “N” and the auxiliary lever 

to the appropriate position. 

7- Check the surroundings when starting, push forward 

the main shift lever slowly to raise the speed 
gradually.

5. Loading/unloading on truck

 

 

 

● 

Do not change the moving direction on 
gangplank. Otherwise, the track may 
break away from the gangplank to cause 
fall-over.

 

● 

An even and safe place without 
hazardous materials around should be 
selected for loading/unloading.

 

● 

Secure the ramp boards hook to avoid 
height difference with the truck body.

 

● 

Do not stand in front of or behind the 
combine to prevent dangers caused by 
sudden sliding.

 

● 

Be careful of the sudden change in gravity 
center when the combine crosses the 
joint between gangplank and truck. 
The machine may fall over especially 
when the moving speed is high. So put 
the auxiliary shift lever to “Low” and 
move slowly. 
(Preparation of truck)

 

● 

The parking brake of truck should be 
locked, and anti-skid devices be placed 
against the wheels.

 

 

 

 



 

Use proper saddle to support the rear part 
of truck body to ensure the body strength. 

 

 



 

Gangplank specification 
Length: Over 4 times of truck body 
height 
Width: Over 45cm 
Strength: Able to bear loads over 
3000kg 
Surface should be roughened and can 
not be too smooth. There should be no 
sharp angles to prevent damaging the 
track. 

 

[Note]

 



 

Operate as specified for traveling above. 



 

Put the range shift lever to “Low”. 



 

Be sure to adjust the engine speed of the 
tachometer in the “Green Zone”. 



 

Perform loading/unloading slowly in the direction of 
lamp boards. Return to original position and adjust 
the direction of the track deviates from the lamp 
boards. 



 

Step the brake pedal to the floor in case of sudden 
stalling of engine or emergency stop. 



 

Step the brake pedal and apply the pedal lock after 
loading on truck. Fold the sunshade after engine 
stalling. 



 

Perform loading/unloading in the moving directions 
listed below.

● 

Secure a strong rope on the “rope hook” 
of the combine.

 

● 

Be sure to keep the traveling direction of 
combine in line with the direction of lamp 
boards to make the track pass through 
the center of lamp boards during 
unloading of the combine. Additionally, 
unload the combine slowly.
